Young adults observe wage rates, interest rates, and child mortality and decide about savings and the quantity and quality of their children. Expenditure on child quality causes human capital accumulation as an external effect. If mortality is high parents prefer to have many children and spend only essential rearing effort. Without human capital(More)
PURPOSE AND METHODS Regional overexpression of the multidrug transporter P-glycoprotein (P-gp) in epileptic brain tissue may lower target site concentrations of antiepileptic drugs and thus contribute to pharmacoresistance in epilepsy. We used the P-gp substrate R-[(11)C]verapamil and positron emission tomography (PET) to test for differences in P-gp(More)
—Honeypots present networked computer systems with known security flaws to attackers and can serve to collect the executable code (malware) aiming to exploit the vulnerability. We describe and evaluate the proof-of-concept NetStage Architecture for a high-speed honeypot realized in reconfigurable logic. Dedicated hardware accelerators for the different(More)
Keywords: Academic self-concept Academic anxiety Short scale Single-item measure Psychological assessment a b s t r a c t Because testing time in educational research is typically scarce, the use of long scales to assess motivational affective constructs can be problematic. The goal of the present study was to scrutinize the psychometric properties of short(More)
Early number competence, grounded in number-specific and domain-general cognitive abilities, is theorized to lay the foundation for later math achievement. Few longitudinal studies have tested a comprehensive model for early math development. Using structural equation modeling and mediation analyses, the present work examined the influence of(More)
The Wisconsin Card Sorting Test (WCST) assesses executive and frontal lobe function and can be administered manually or by computer. Despite the widespread application of the 2 versions, the psychometric equivalence of their scores has rarely been evaluated and only a limited set of criteria has been considered. The present experimental study (N = 100(More)
OBJECTIVE To investigate whether childhood general intelligence, fluid intelligence (Gf), and crystallized intelligence (Gc) predict various health outcomes in middle adulthood. METHOD This prospective longitudinal study followed a nationally representative sample of 717 Luxembourgers. Intelligence and socioeconomic status (SES) were measured at age 12;(More)
Computer-based problem solving scenarios or " microworlds " are contemporary assessment instruments frequently used to assess students' complex problem solving behavior – a key aspect of today's educational curricula and assessment frameworks. Surprisingly, almost nothing is known about their (1) acceptance or (2) psychometric characteristics in student(More)
